Patent FR-2319861-A1 (FR)
Title: Thermodynamic system functioning as heat pump - uses medium of non:azeotropic mixture formed of pure and stable elements
Inventor: TRICHET JEAN
IPC: F25B9/00
Filed: 1975-08-01
Abstract: The thermodynamic system functions as a heat pump, compressing a medium in the gaseous state, this being then condensed by yielding up heat to a heat source. Part at least of the medium when condensed is expanded at low pressure, and then vapourised by deriving heat from a cold source, after which the vapour is recompressed. The medium used is a non-azeotropic mixture containing a number of pure elements, which are thermally and chemically stable at the various temperatures and pressures in the cycle. When partly condensed or vapourised, it comprises single vapour and liquid phases, both homogeneous. The elements are so selected as to give a mixture which is at least partly vaporisable and condensable, and to be always soluble in mixture in the liquid state.

Title: Imitation wood grain on thermoplastic film - with point-simulating impression areas and printed image
IPC: B44F9/02
Filed: 1975-09-10
Abstract: Imitation wood grain surface is produced on thermoplastic film by photographically providing colour separations of a wood original, forming printing cylinders according to the colour separations, and printing the grain onto the film by a multi-colour printing process. The film is then impressed to simulate pores with a stamping cylinder of which the pattern is produced from a colour separation of the wood original, and the stamped areas are filled with dye. A transparent film or lacquer may be applied to the printed side prior to stamping.

Title: Baked loaves transfer station - with light barrier before and proximity switch after mechanical stop at loaf transfer (BE030876)
IPC: A21C15/00
Filed: 1976-02-02
Abstract: Parent patent describes a transport system with chutes and conveyors which conveys baked loaves of bread from the baking oven to a cooling section. They are separated one-by-one and transferred intermittently to the cells of the next processing machine. The transfer station to the next processing macine is now fitted with a stop which can be actuated with a given repetition frequency. A signal transmitter ahead of the stop indicates whether the space ahead is engaged or not. This treats the loaves more gently and transfers them in the precise cycle to the next processing machine. It functions reliably and reqires little engineering effort. The system operates trouble free and requires no maintenance.

Title: Thread coiling machine with controlled centrifugal pressure - monitors centre distance between coiling spindle and contact drum by means of air jet sensor (BR 8.2.77)
IPC: B65H54/52
Filed: 1976-06-11
Abstract: A thread coiling machine (1) has a coiling spindle (11) located by a support yoke (2). A contact drum (8) is carried by an adjustable support (9). Both axes of coiling spindle and contact drum are able to regulate the centre distance between them. As the coil grows, the support pistons (4, 5) of the spindle plate (2) retract, thus increasing the centre distance. If the contact pressure on contact drum (8) is excessive, the membrane cylinder (17) allows the drum (8) to retract. An air jet sensor (18) monitors the position of the contact drum and operates the valve (19) accordingly.

Title: Lifting gear for precision positioning of load - has mercury floating in tube between contacts to sense small pressures when manoeuvring
IPC: B66C13/04
Filed: 1976-07-15
Abstract: The lifting gear is used for precision positioning of a load and comprises a compressed air cylinder suspended vertically to carry a motorised lifting drum (4). The piston initially lifts the load approximately into position. The air also acts on both sides of a U-shaped tube (17) filled with mercury and when air is shut off, the system is in balance. Power cylinders then partly rotate the main cylinder about its vertical axis to break any friction seal. Downward or upward pressure (f9) on the load unbalances the column, mercury floating between electrical contacts (Co, Cl) to operate the cabld drum in the same direction (f10).

Title: Display of digital values as curves - on TV raster scanning display with beam brightness increased at intersection points (NL150377)
IPC: G09G1/16
Filed: 1976-09-01
Abstract: A method of displaying digital values as points of a curve on the screen of a display using a raster scanning process is designed to produced improved visibility of the curve. The screen of a t.v. tube is scanned by an electron beam which is synchronised with two counters, one indicating the line being scanned and the other the position of the beam in that line. When the counter conditions agree with the coordinates of a digital value the brightness of the beam is increased to produce a visible point. To increase visibility of curve points, several neighbouring raster points are illuminated per curve point. Neighbouring curve points may share a common raster point.

Title: Lampshade raising and lowering mechanism - uses vertical helical wire and wire loop trapped between coil and shade
IPC: F21V17/02
Filed: 1977-01-10
Abstract: A method of controlling movement of a shade over a lamp, e.g. for altering the colour, employs a screw drive which raises and lowers the shade or in an alternative design rotates the shade. The shade (3) can be guided vertically by vertical wires (12) forming a cage, and the screw is a spiral wire (1) alongside. This spiral is mounted between a top support (4) above the lamp and a bottom support (11) below the bottom limit or travel. These supports fix the position of the spiral but allow it to be rotated about its axis by a suitable drive. A loop of wire (2) passing through the shade, and a corresponding number of coils, raises or loweres the shade as the coil is rotated. In an alternative design rotating the shade, the coil drives the shade from an alongside position.

Title: Making elastic covers for holding tyre retreads during vulcanisation - with cover thickness variations to enhance cover life
IPC: B29D30/56
Filed: 1977-04-26
Abstract: An elastic envelope or cover for enclosing a combination of a tyre carcass and a prefabricated tread hoop for retread vulcanisation, where the toroidal cover has a 'U' cross-section of non-uniform wall thickness, being relatively thick along the region in contact with the tread zone. Also describes an extrusion die with an adjustable offset and assymetric conical mandrel for extrusion of a profile of suitably varying wall thickness which can be slit longitudinally and then transversely for making such envelopes. Alternatively the envelope may be extruded as a flat or 'U' profile which is relatively thick along its central zone. Used for supporting tread/carcass combinations involving casing in autoclaves at e.g. 98-148 degrees C with the carcasses pressurised to higher pressures than the pressures in the surrounding over chamber. The greater strength and tear resistance of the thicker envelope wall alongside the enclosed tread prolongs the life of the cover against damage caused by repeated fitting and stripping.
